Definitions

  • the invention relates to a front machine for a touring ski binding.
  • This front machine comprises two levers arranged laterally, viewed in the longitudinal direction of the ski, opposite one another, each with a holding means for holding a ski boot in a toe area of the ski boot.
  • the two levers are each mounted pivotably about an axis in such a way that the holding means are moved in a transverse direction of the ski when the levers pivot about these axes.
  • the front-end machine has a release position in which the two holding means are at a first distance from one another. It also has a holding position in which the two holding means are at a second distance from one another, which is smaller than the first distance.
  • ski bindings can be subdivided into piste bindings, which are only used for downhill and skiing on ski lifts, and touring bindings, which are also used for walking on skis, in particular for climbing with the help of climbing skins attached to the skis. While the former only has to ensure a reliable fixation of the ski boot on the ski in a so-called downhill position, the latter must also be able to be brought from the downhill position to an ascent position in which the ski boot can be swiveled about an axis in the transverse direction of the ski and lifted off the ski in the heel area to allow articulation between the ski boot and ski for walking.
  • Touring ski bindings can be divided into two types.
  • One type comprises a ski boot carrier which can be pivoted relative to the ski and on which the ski boot is held by binding jaws.
  • a representative member of this type of touring ski bindings is in the EP 0 754 079 B1 (Fritschi AG ) described.
  • the second type of touring ski bindings does not include such a ski boot carrier.
  • the ski boot is pivotably mounted in a toe area on the sole in a ski-mounted front machine.
  • the automatic heel unit is also firmly attached to the ski at a distance from the automatic front unit that is adapted to the length of the ski boot sole and locks the shoe in the heel area in the downhill position.
  • ski boots typically have two lateral recesses in the toe area for pivotable mounting in the front automat. In the heel area, recesses open to the rear are formed on the shoe sole, into which retaining means of the automatic heel unit can engage.
  • ski boots have a stiff or only slightly bendable sole. In the latter case, the ski boots can be designed to be flexible, for example in the ball of the foot.
  • a (fictitious) ski is often used as a reference system to describe such binding systems, it being assumed that the binding is mounted on this ski. This habit is taken over in the present text.
  • the term "longitudinal direction of the ski” means along the alignment of the longitudinal axis of the ski.
  • "parallel to the ski” means oriented along the longitudinal axis of the ski for an elongate object. For a flat object, however, the term “parallel to the ski” means aligned parallel to the sliding surface of the ski.
  • transverse direction of the ski means a direction transverse to the longitudinal direction of the ski, which, however, does not have to be oriented precisely at right angles to the longitudinal axis of the ski.
  • ski center in turn means a center of the ski, seen in the transverse direction of the ski, while the term “ski fixed” means not movable with respect to the ski. It should also be noted that terms that do not contain the word “ski” also refer to the reference system of the (fictitious) ski.
  • front”, “rear”, “top”, “bottom” and “side” refer to “front”, “back”, “top”, “bottom” and “side” of the ski.
  • terms such as “horizontal” and “vertical” also relate to the ski, where “horizontal” means lying in a plane parallel to the ski and “vertical” means oriented perpendicular to this plane.
  • a touring ski binding of the second type introduced above is in the EP 0 199 098 A2 (Bartel ) and is sold under the Dynafit brand.
  • the binding front part of this system comprises two angled levers which are arranged opposite one another in the transverse direction of the ski and are each mounted pivotably about an axis running in the longitudinal direction of the ski.
  • the two angle levers each have an upward and a sideways arm, which are arranged at right angles to one another.
  • the upwardly directed arms each comprise a truncated cone or hemispherical pin which points towards the center of the ski and which can engage in recesses provided for this purpose in the toe area of a ski boot.
  • the side-facing arms of the angle levers point towards the center of the ski, but are in operative connection with one another via a spring device. Since the two angle levers are mutually spring-loaded by the spring device via the sideways arms, they can move downwards and downwards by overcoming a dead center position in which the two sideways arms are aligned in a linear extension to one another snap up. When the side-facing arms are snapped down, the upward-facing arms are pivoted together. On the other hand, when the sideways arms are snapped up, the upward arms are pivoted apart. Accordingly, the pins for holding a ski boot are closer together in the first case and further apart in the second case.
  • a ski boot can be held or pivotably mounted between the two angle levers by means of the pins. Therefore this position of the binding front part is a holding position. In the second case, however, the holding means are far enough apart so that the ski boot is released. Correspondingly, this position of the binding front part is a release position.
  • this includes in FIG EP 0 199 098 A2 (Bartel ) described binding front part an opening lever which is pivotable about an axis aligned in the transverse direction of the ski and which engages around the connection of the two laterally aligned arms of the angle lever above and below.
  • an opening lever which is pivotable about an axis aligned in the transverse direction of the ski and which engages around the connection of the two laterally aligned arms of the angle lever above and below.
  • the ski boot can also be released from the ski binding system without operating the opening lever.
  • the ski boot is first released from the automatic heel and then from the binding front part. If it is a frontal fall, the ski boot is released upwards by the automatic heel unit and tilted forward in the binding front part. If the force acting forwards or upwards on the ski boot is sufficiently great, the ski boot is also torn from the binding front part in that the force acting on the two angle levers is overcome. If, on the other hand, it is a case of a lateral fall, the ski boot is released in a lateral direction by the automatic heel and is released in the toe area of the ski boot Rotated vertical axis. The ski boot is released from the front part of the binding in a rotating manner by overcoming the force acting on the angle lever.
  • Both the binding front part according to EP 0 199 098 A2 (Bartel ) as well as the binding front part according to FIG WO 2009/121187 A1 (G3 Genuine Guide Gear Inc.) have the disadvantage that tripping occurs in an uncontrolled manner.
  • the two angle levers When triggered, the two angle levers are pushed apart in an undefined manner by a force (or torque) acting on the ski boot, as a result of which the ski boot is released from the binding front part.
  • This front-end automaton also includes two angle levers, each of which includes two arms which are arranged essentially at right angles to one another.
  • the first arms of these angle levers also each comprise a truncated cone or hemispherical pin, pointing towards the center of the ski, for holding a ski boot.
  • the second arms of these angle levers are also aligned laterally to the center of the ski, pointing towards one another.
  • the two angle levers are pivotably mounted about vertical axes, the axes in front of the Toe area of the ski boot are arranged.
  • the second arms of the angle levers are not in a direct operative connection, but each engage with their end in a lateral incision of a pivot lever aligned in the longitudinal direction of the ski.
  • This pivot lever is displaceable in the longitudinal direction of the ski, the ends of the second arms of the two angle levers being carried along in the lateral incisions.
  • the two angle levers are pivoted towards each other or apart, as a result of which the front-end machine is transferred from the release position to the holding position and back.
  • the pivoting lever is mounted on the front-end machine so that it can pivot about a vertical axis, but it is pressed into an alignment parallel to the ski by two springs.
  • the outer of the two angle levers can therefore be pushed outwards by pivoting the pivot lever slightly against the spring force until the angle lever is released from the lateral incision in the pivot lever.
  • the inner angle lever is pivoted slightly inwards by the pivoting movement of the pivot lever following the outer angle lever.
  • the object of the invention is to create a front-end machine belonging to the technical field mentioned at the beginning, which increases the safety for a skier.
  • the holding means are pins which are arranged on the respective lever in such a way that, starting from the respective lever, they point with a free end towards the center of the ski.
  • the front-end machine includes a positive control on which the two levers are mounted in the holding position, so that the two levers can be coupled in a dynamic range in the transverse direction of the ski and the two holding means are coupled at a second distance from each other on a dynamic path in the transverse direction of the ski, wherein the front machine has a safety release position and the two levers in the holding position can be moved to one end of the dynamic range, where that of the two levers which comprises the holding means, which is moved away from the center of the ski on the dynamic path, can be released from the forced control and from the other of the two levers can be pivoted away, as a result of which the front-end machine can be brought from the holding position into the safety release position.
  • the coupled movement of the two levers along the dynamic range can be, for example, a pivoting movement of the two levers about the axes.
  • the coupled movement of the two levers along the dynamic range can also be, for example, a linear movement along a linear path, which corresponds to a translational movement of the two levers, in which the two levers are coupled and shifted in the transverse direction of the ski.
  • the coupled movement of the two levers along the dynamic range can also be, for example, a linear movement along a linear path, which is a combination corresponds to a translational movement and a pivoting movement of the two levers, in which the two levers are coupled in the transverse direction of the ski and are pivoted about the axes.
  • the dynamic range can be limited on one or both sides by a stop by which at least one of the two levers is stopped and its further freedom of movement is prevented.
  • the dynamic range is limited on one or both sides in that the two levers are no longer coupled from a certain position, but can be moved decoupled.
  • the dynamic range for one of the levers is limited by a stop and for the other the lever is limited by the fact that it can be moved in a decoupled manner from a certain position.
  • the type of limitation for the two levers can also be dependent on the side of the dynamic range.
  • the dynamic range is limited on a first side for a first of the two levers by a stop and for a second of the two levers is limited by the fact that it can be moved in a decoupled manner from a certain position.
  • the dynamic range on a second side for the first lever can be limited in that it can be moved decoupled from a certain position, while the dynamic range on the second side for the second lever is limited by a stop.
  • the solution has the advantage that a ski boot held in the front machine can be moved together with the two holding means in the holding position on the dynamic path in the transverse direction of the ski. Through this movement, energy can be absorbed by the front machine without the ski boot being released from the front machine. This is advantageous when skiing and, if necessary, in the event of a fall, since blows can occur on the ski or the ski boot, in which the ski boot should not become detached from the front machine.
  • the energy that can be absorbed by the front-end machine can be specified by adapting the length of the dynamic path and / or a resistance force that must be applied for the movement. Accordingly, a controlled Safety release can be provided, which is triggered when the energy of a blow should exceed the absorbable energy.
  • the two levers are coupled within the dynamic range and can be pivoted about the axes in the transverse direction of the ski. This has the advantage that the movement of the two levers is guided by the axes.
  • the two levers are coupled within the dynamic range and can be moved in the transverse direction of the ski along a linear path.
  • This can be, for example, a translational movement of the two levers, in which the two levers are coupled and moved in the transverse direction of the ski.
  • This has the advantage that, in the holding position, a stable connection can be specified between the two levers which holds the two holding means on the levers at a second distance from one another.
  • the movement of the two levers along the linear path can also be, for example, a combination of a translational movement and a pivoting movement of the two levers, in which the two levers are coupled, moved in the transverse direction of the ski and pivoted about the axes.
  • the dynamic path of the holding means can be designed in such a way that forces which act from different directions on a ski boot held in the front machine can be optimally absorbed by the front machine.
  • the front-end automat for a ski binding comprises two levers arranged laterally in the longitudinal direction of the ski, each having a holding means for holding a ski boot in a toe area of the ski boot.
  • the two levers are preferably each pivoted about an axis and the holding means are moved by the levers in a pivoting movement in a transverse direction of the ski, the front-end machine preferably comprising an element called a positive control and the two levers on this positive control and on another element of the Front automats are storable.
  • the front-end machine preferably has a release position in which the two holding means are at a first distance from one another.
  • the automatic front-end device preferably has a holding position in which the two holding means are located at a second distance from one another, which is smaller than the first distance.
  • the two levers are advantageously movably mounted on the positive control, which is also movable in the holding position.
  • the two levers can be pivoted in the transverse direction of the ski, coupled within a dynamic range, preferably coupled by the movable positive control, the two holding means being coupled at a second distance from one another on a dynamic path in the transverse direction of the ski.
  • the priority control is moved is not specified. For example, it can be a linear movement or a pivoting or rotary movement.
  • the front-end automaton for a ski binding comprises two levers arranged laterally in the longitudinal direction of the ski, each having a holding means for holding a ski boot in a toe area of the ski boot.
  • the two levers are preferably each pivotably mounted about an axis and the holding means are moved by the levers in a pivoting movement in a transverse direction of the ski, the front-end machine preferably comprising an element called a positive control and the axes being mounted on this positive control.
  • the front-end machine preferably has a release position in which the two holding means are at a first distance from one another.
  • the automatic front-end device preferably has a holding position in which the two holding means are located at a second distance from one another, which is smaller than the first distance.
  • the two levers are advantageously mounted on the positive control, which is movable in the holding position. In this case, the two levers can be moved in a coupled manner in the transverse direction of the ski within a dynamic range, the two holding means being coupled at a second distance from one another on a dynamic path in the transverse direction of the ski.
  • How the priority control is moved is not specified. For example, it can be a linear movement or a pivoting or rotating movement.
  • preferred embodiments of the front-end machine can also be designed differently. In the following it is shown on the basis of advantageous features how such other preferred embodiments can be designed. Of course, the two preferred embodiments mentioned above can also include one or more of these advantageous features.
  • the axes of the levers are advantageously arranged in a plane parallel to the ski. This has the advantage that the axles can be arranged below the holding means, as a result of which a compact design of the front-end machine is achieved.
  • the axes are preferably aligned essentially parallel to the ski, although deviations from an alignment parallel to the ski of 10 degrees or of 20 degrees can be provided. Preferably, however, the lateral deviation of the axes from an orientation parallel to the ski is less than 10 degrees.
  • the levers are pivotable within the dynamic range and accordingly the dynamic path of the holding means lies in a plane perpendicular to the axis of the respective lever, a plane of the dynamic paths of the holding means is thereby oriented essentially in the transverse direction of the ski. If, on the other hand, the two levers are coupled within the dynamic range and can be moved in the transverse direction of the ski along a linear path, the movement of the holding means in the transverse direction of the ski can be continued by aligning the axes when the levers pivot about the axes. In both cases, this arrangement of the axes is advantageous in the event that the front-end machine provides for a lateral safety release.
  • a movement of the ski boot runs essentially in a plane parallel to the ski.
  • the movement of the ski boot can include both a linear movement and a rotation about a vertical axis of the ski boot. Since the plane of the dynamic path is thus oriented essentially at right angles to the plane of movement of the ski boot, the dynamic path of the holding means can best accommodate movements of the ski boot which are caused by differently oriented forces acting in the transverse direction of the ski.
  • the energy that can be absorbed by the front-end automaton can be specified in the best possible way for various forces. By specifying the absorbable energy, a controlled, lateral safety release can in turn be made possible, which occurs when the absorbable energy is exceeded.
  • the axes are aligned differently.
  • they can also be oriented vertically or at any desired angle to the longitudinal direction of the ski.
  • both levers each include a control jaw on a side facing the center of the ski for interacting with a ski boot.
  • These control jaws can, for example, each be an element which is attached to the corresponding lever and protrudes towards the center of the ski.
  • the control jaws have the advantage that with a pivoting movement of the two levers from a certain pivoting angle, the control jaw of the lever lying in the direction of movement can interact with the ski boot and the holding means of this lever can thereby be released from the ski boot. Accordingly, this has the advantage that the process of a lateral safety release from the front machine can be simplified.
  • the sequence of movements of the ski boot becomes more continuous in the case of a lateral safety release and thus the safety for the skier is increased.
  • the levers can be pivoted about the axes within the dynamic range, the control jaws can interact with the ski boot during a pivoting movement of the levers within the dynamic range.
  • the two levers can be moved along a linear path within the dynamic range and, for example, at least one of the two levers can be pivoted about the corresponding axis in the event of a lateral safety release, the corresponding control jaw can interact with the ski boot during the safety release, making the ski boot easier can be released from the front machine.
  • control jaws are not designed as a separate element.
  • they can each be produced in one piece together with the corresponding lever, or the levers can also be shaped in such a way that, for example, a bow in the lever takes on the function of a control jaw.
  • the levers comprise an arch like the steering jaw, which is also to be understood under the term steering jaw.
  • the two levers cannot include any control jaws arranged on the side of the levers which is directed towards the center of the ski. If the holding means are designed, for example, in such a way that they are easily detached from the ski boot when the levers are pivoted beyond a certain angle, this alternative can be advantageous since it simplifies the construction of the front-end automaton and makes it more cost-effective to manufacture.
  • the positive control can preferably be moved along a positive control path, as a result of which the two levers can be coupled within the dynamic range. If the two levers can be moved along a linear path within the dynamic range, the two levers are preferably fixedly mounted on the positive control in the holding position, as a result of which the two levers can be coupled within the dynamic range. If, on the other hand, the two levers can be pivoted about the axes within the dynamic range, the forced control in the holding position can preferably be moved along a forced control path with a coupled pivoting movement of the two levers within the dynamic range of the two levers. How the priority control is moved exactly in these two cases is not specified.
  • Their movement can be, for example, a movement in a linear direction, a pivoting or rotary movement, or a combination thereof. If the movement of the forced control is a rotary or pivoting movement, the forced control path can thus be an angle of rotation. If, on the other hand, the movement is a combination of a linear direction as well as a pivoting or rotary movement, the forced control path can be a combination of an angle of rotation and a linear path. In the case of such a combination, there is also the possibility, for example, that the positive control is moved as a whole in a combined movement. However, there is also the possibility, for example, that one or more elements of the priority control are moved in a linear direction, while one or more additional elements of the priority control are rotated or pivoted. All such movements of the positive control along the positive control path have the advantage that in the holding position a coupled one in a simple manner Pivoting movement of the two levers along the dynamic range can be achieved.
  • the movement of the positive control is a movement in a linear direction, a pivoting movement or a combination thereof
  • the movement and thus also the positive control path are preferably oriented in the transverse direction of the ski. This has the advantage that the forced control can join in with the coupled pivoting movement of the two levers, which simplifies the construction of the front-end machine.
  • the positive control is not movable in the holding position, but is arranged in a ski-mounted manner.
  • the positive control can be moved in the holding position, it can be pushed towards the center of the positive control path with a force if it deviates from a center of the positive control path, preferably by a pretensioned elastic element.
  • a pretensioned elastic element preferably by a pretensioned elastic element.
  • elastic element there is more than one pre-tensioned, elastic element. Regardless of the number of elastic elements, this has the advantage that the positive control is moved from the elastic element or elements to the center of the positive control path when no other force acts on the positive control.
  • the two levers can also be moved to the center of the dynamic range with the forced control.
  • the two levers can be moved from this center of the dynamic range both in a first and in a second direction along the dynamic range under the action of an incipient lateral force, moving them back to the center of the dynamic range when the lateral force ceases will. If there is a laterally directed impact or a laterally directed force on the ski boot or ski when skiing, the corresponding energy can be absorbed by the front-end machine without detaching the ski boot, regardless of which side the impact or the force comes from.
  • the mentioned center of the positive control path and the mentioned center of the dynamic range can be the geometric center of the Act override control path or dynamic range. However, it can also be a point in the positive control path or dynamic range that is not in the geometric center. It is possible that these centers lie in a continuous area of the override control path or dynamic area. In this case, the centers are given by the fact that the positive control or the levers are pressed by the elastic element or elements at this point in the positive control path or in the dynamic range. But there is also the possibility that the centers are in a kink in the override control path or dynamic range.
  • the positive control path can be v-shaped and the center of the positive control path can be at the apex of the "v".
  • the restraint can be moved along one or the other arm of the "v" from the center of the restraint path depending on the direction of the lateral force or the lateral impact.
  • the middle of the positive control path can also be located at one end of the positive control path. This can be the case in particular when the forced control path runs along the longitudinal direction of the ski.
  • the positive control can be moved in the longitudinal direction of the ski, but in this example the two levers are mounted on the positive control in the holding position in such a way that they can be pivoted in the effective direction of the lateral force or the lateral impact, while the positive control is moved in the longitudinal direction of the ski regardless of the effective direction of the lateral force.
  • the prestressed elastic element is preferably in the center of the ski in the longitudinal direction of the ski aligned.
  • the pretensioned, elastic element presses on the positive control in the longitudinal direction of the ski by pressing a laterally guided and thus laterally non-displaceable piston into a horizontally arranged, essentially V-shaped indentation in the positive control.
  • the positive control that can be moved in the transverse direction of the ski can be held in the middle of the positive control path by pressing the piston into a tip of the V-shaped indentation.
  • the positive control can be moved starting from the center of the positive control path along the positive control path, the piston being pressed by the corresponding flank of the essentially V-shaped indentation in the longitudinal direction of the ski against the pretensioned force of the elastic element.
  • the force of the elastic element acting via the piston on the flanks of the essentially V-shaped indentations and directed in the longitudinal direction of the ski causes a restoring force which drives the positive control back to the center of the positive control path.
  • the piston can have a roller bearing at its tip, which can roll on the flanks of the essentially V-shaped indentation in the positive control.
  • the piston does not have a roller bearing, but that the piston and / or the essentially V-shaped indentation in the positive control have a special coating which reduces the frictional resistance.
  • the piston has a roller bearing at its tip, which can roll on a special coating of the essentially V-shaped indentation in the positive control.
  • the piston does not include such a roller bearing and that neither the piston nor the essentially V-shaped indentation in the positive control have a special coating.

Because of the flank of the indentation 25, which is oriented obliquely to the spring force, a restoring force is exerted on the control plate 20.3, which drives the control plate 20.3 back into its ski-centered position.
  • This restoring force and the path which a ski boot stored in the front machine 1 covers from its central ski position to the end of the dynamic path gives maximum energy, which the front machine 1 can accommodate without a lateral safety release occurring.
  • This maximum energy can be adjusted by the preloading of the spiral spring 36 by means of the adjustment screw 38 and the locking nut 37.

  • the control lever 3 is pressed down by the toe area 102 of the ski boot 100 from the blocking position into the holding position, whereby the front-end machine 1 is transferred from the blocking position to the holding position. If the ski boot is now tilted further forward, the control lever 3 is pressed a little further down.
  • the two pivot levers 5.1, 5.2 are pivoted apart and the ski boot 100 is released from the automatic front machine 1. For this purpose, the control lever 3 does not have to be pushed completely from the holding position into the release position and the front-end machine 1 does not have to be completely transferred into the release position. It is sufficient if the ski boot 100 presses the control lever 3 downwards slightly, starting from the holding position, and the two pivot levers 5.1, 5.2 are pivoted apart a little.

  • the front machine 1 enables a lateral safety release in the holding position. If a ski boot 100 is stored in a touring ski binding system with the front machine 1 and the touring ski binding system is in the downhill position, the touring ski binding system thereby enables a lateral safety release. If, for example, the ski boot 100 is mounted on the automatic heel unit by holding spurs pointing from the back to the front, the ski boot 100 can perform a rotary movement in the event of such a lateral safety release. It is only released from the side of the automatic heel unit 1 while it is still held by the holding spurs of the automatic heel unit.
  • the ski boot 100 As soon as the ski boot 100 is released from the automatic heel unit 1, it can also be released from the automatic heel unit by being moved or rotated away from the holding spurs of the automatic heel unit. Accordingly, there is no need for a lateral safety release option using the automatic heel unit. It is sufficient if the automatic heel enables a safety release in the forward direction.
  • the front automat 1 is optimized for a lateral safety release in a touring ski binding system in which the heel automat does not allow a lateral safety release.
  • This optimization is in the Figure 10 which shows a plan view of the front machine 1 in the holding position with the ski boot 100 held therein, illustrated. So are in the Figure 10 two dashed straight lines are shown along which the axes 9.1, 9.2 (see Figure 3 ), about which the two pivot levers 5.1, 5.2 are pivotable, are aligned. These two straight lines 15.1, 15.2 run together at an angle of 6 degrees to the longitudinal axis of the ski and intersect at a point 16 in the heel area of the ski boot 100.
  • the ski boot 100 Since the automatic heel unit does not allow a lateral safety release, the ski boot 100 is rotated around a vertical axis when the safety release is from the side rotated near the point 16 until it is released from the front machine 1. As a result, the pivoting movement of the pivoting lever 5.1, 5.2 lying in the direction of movement runs perpendicular to the direction of movement of the ski boot 100.

  • one surface of the slide 420.4 has a recess 425.1, 425.2 on each side, from which the stops 412.1, 412.2 of the pivoting lever 405.1, 405.2 can be moved upwards when the corresponding pivoting lever 405.1, 405.2 is tilted away laterally in the event of a lateral safety release.
  • the two side levers 405.1, 405.2 each have a cover 413.1, 413.2 at the level of the axes 409.1, 409.2.
  • covers 413.1, 413.2 each extend a little closer to the center of the ski than the stop 412.1, 412.2 of the corresponding pivot lever 405.1, 405.2 and fill the recesses 425.1, 425.2 in the surface of the slide 420.4 in the holding position and in the release position of the front-end machine 401. So that these covers 413.1, 413.2 do not hit the sole of a ski boot held in the ski binding from below in the event of a lateral safety release, the upper areas of the pivot levers 405.1, 405.2 are bent backwards so that the two holding spurs 406.1, 406.2 are located behind the stops 412.1, 412.2 and the covers 413.1, 413.2 are located. This ensures that the cover 413.1, 413.2 of the pivoting lever 405.1, 405.1 that tilts away to the side can be pivoted upwards in front of the sole of the ski boot in the event of a lateral safety release.
  • the front automat 301 shown is that the front automat 401 comprises not just one, but two base plates 430.1, 430.2 and a holding element 430.3.
  • a first base plate is used 430.1 as a guide for moving the slide 420.4 in the transverse direction of the ski.
  • a second base plate 430.2 also has two openings 431.2, 431.3 in its front area, through which screws can be passed to fasten the front-end machine 401 on a ski.
  • This second base plate 430.2 is arranged behind the first base plate 430.1 and serves as a base for the holding element 430.3, which also has two openings 433 for attachment to a ski.
  • This holding element 430.3 is formed from a piece of sheet metal. In a cross-section oriented vertically in the transverse direction of the ski, this holding element 430.3 essentially has a U-shape, the two upper edges being bent inward. As a result, the holding element 430.3 forms a rail-like longitudinal guide for the housing 402 of the front-end machine 401, the housing 402 of the front-end machine 401 not being able to be moved upward relative to the holding element 430.3.
  • the front-end machine 401 is mounted on a ski
  • four screws are passed through four vertically oriented openings 432.1, 432.2, 432.3, 432.4 arranged in the housing 402 and screwed tightly to the ski.
  • the two front screws run both through the two front openings 432.1, 432.4 of the housing 402 and through the two openings 431.1, 431.4 of the first base plate 430.1 and hold the housing 402 and the first base plate 430.1 firmly on the ski.
  • the two rear screws are passed down through the rear openings 432.2, 432.3 of the housing 402 when the front machine 401 is fastened, where they run through the two openings in the holding element 430.3 and through the two openings 431.2, 431.3 of the second base plate 430.2 and only hold the holding element 430.3 and the second base plate 430.2 on the ski. Therefore, in the assembled state, when the front machine 401 is attached to a ski, the housing 402 is only screwed to the ski by the two front screws.
  • the rear region of the housing 402 is held in the longitudinal guide of the holding element 430.3 screwed tightly to the ski and can move in the longitudinal direction of the ski relative to the holding element 430.3.
  • a third essential difference between the front automat 401 shown here and the one in the Figures 14a to 24c and 25 to 27c shown front automats 201, 301 is that the front automat 401 has a damper position instead of a blocking position.
  • the control lever 403 of the front automatic machine 401 shown here does not include a bolt with which a movement of the slide 420.4 in the transverse direction of the ski can be blocked.
  • the control lever 403 comprises two bulges 428.1, 428.2 which press from the front against a front side of the carriage 420.4 when the control lever 403 is moved upwards into a damper position.
  • a movement of the slide 420.4 in the transverse direction of the ski is subject to increased resistance to movement due to friction.
  • the slide 420.4 can be moved less well in the transverse direction of the ski in the damper position of the front-end machine 401. If, therefore, the damper position is used when climbing, the ski is prevented from slipping back and forth with respect to the ski boot held in the automatic front device 401. Correspondingly, the step security for the skier is increased by the damper position. At the same time, a lateral safety release can still take place in the damper position, whereby the safety for the skier is also guaranteed in the damper position.
  • FIGS. 29a, 29b and 29c each show a bottom view of a horizontally aligned cross-section through the front automat 401, which runs through the pivoting element 420.3 and through the horizontal slot 420.5 in the slide 420.4.
  • the swivel element 420.3 is mounted on the slide 420.4 so that it can pivot about a first vertical axis 448, as was already the case with the two front-end machines 201, 301, the first vertical axis 448 being displaceable in the longitudinal direction of the ski relative to the slide 420.4.
  • the pivot element 420.3 is mounted behind the slide 420.4 pivotably about a second vertical axis 449 on the housing 402 of the front-end machine 401, the second vertical axis 449 being displaceable relative to the housing 402 in the longitudinal direction of the ski.
  • the pivot element 420.3 has an elongated shape. A longitudinal axis of the pivot element 420.3 is aligned parallel to the longitudinal direction of the ski when the positive control 420 is located in the middle of the positive control path. In a rear region, the pivot element 420.3 has two feet which protrude laterally from the longitudinal axis of the pivot element 420.3 and point obliquely backwards.
  • the swivel element 420.3 is supported against a metal front side 437 of the piston 435.
  • the support of the pivot element 420.3 against the piston 435 works like the pivot element 43 in the Figures 12a, 12b and 12c shown variant of the front automaton 1.
  • the pivot element 420.3 is arranged somewhat in front of the first vertical axis 448 and has two arms 440.1, 440.2 which are directed slightly forward and project laterally from the longitudinal axis of the pivot element 420.3. These two arms 440.1, 440.2 have outer ends which are rounded and are bent towards each other from the rear to the front from the outside to the side of the ski.
  • the pivot element 420.3 further comprises a head 441 arranged between its two arms 440.1, 440.2.
  • This head 441 is arranged in front of the first vertical axis 448 and has a forward-facing side with a latching position. A flat area of this forward-facing side is oriented essentially perpendicular to the longitudinal axis of the pivot element 420.3.
  • the control lever 403 presses against the head 441 of the pivot element 420.3.
  • the leg element 420.3 is moved to the rear together with the piston 435 against the spring force of the spiral spring 436 compared to the holding position.
  • the two arms 440.1, 440.2 of the pivot element 420.3 are also moved to the rear with respect to the stops 412.1, 412.2 of the pivot levers 405.1, 405.2. This leads to the fact that the outer ends of the two arms 440.1, 440.2 that are bent towards the front towards the middle of the ski give the stops 412.1, 412.2 more space for a movement towards the middle of the ski, compared to the holding position.
  • the two pivot levers 405.1, 405.2 are each by a leg spring 429.1 429.2 with a applied outward force.
  • the pivot levers 405.1, 405.2 are also pivoted as far apart as possible in the release position and the two stops 412.1, 412.2 abut against the outer ends of the two arms 440.1, 440.2. This means that the two holding spurs are at the first distance from one another.
  • the control lever 403 does not press against the head 441 of the pivot element 420.3.
  • the pivot element 420.3 is moved forwards by the spiral spring 436 and the piston 435 as far as the mounting of the first vertical axis 448 in the slide 420.4 allows.
  • the head 441 of the pivot element 420.3 is just inside the front side of the carriage 420.4.
  • the two arms 440.1, 440.2 of the pivot element 420.3 are so far forward in the carriage 420.4 that the stops 412.1, 412.2 of the two pivot levers 405.1, 405.2 in the rear area of the outer ends of the arms 440.1, 440.2 butt against the outer ends of the arms 440.1, 440.2. Since the outer ends of the two arms 440.1, 440.2 are most distant from one another in their rear region, the stops 412.1, 412.2 are also moved further apart in comparison to the release position. This means that the pivot levers 405.1, 405.2 are pivoted together, so that the two holding spurs are located at a second distance from one another.
  • the pivoting lever 405.1 Since the pivoting lever 405.1 is thus released from the pivoting element 420.3, it is pivoted outwardly by the leg spring 429.1 with the retaining spur, while its stop 412.1 is moved towards the center of the ski. Because the stop 412.1 is located in front of the arm 440.1 of the pivot element 420.3, the stop 412.1 prevents the arm 440.1 of the pivot element 420.3 from being able to be moved forward again. Accordingly, movement of the positive control 420 back to the center of the positive control path is blocked as a result.
  • the pivot levers 405.1, 405.2 can be pivoted against the spring force of the leg springs 429.1, 429.2 with the holding spurs towards the center of the ski. If, therefore, a ski with the front machine 401 falls over and hits a pivot lever 405.1, 405.2, the corresponding pivot lever 405.1, 405.2 can be pivoted inwards towards the center of the ski, which reduces the risk of damage to the front machine 401.
  • FIGS 30a, 30b and 30c each shows a vertically aligned cross section of the front-end machine 401 arranged in the center of the ski and running in the longitudinal direction of the ski.
  • the front machine 401 is on the left, while the front machine 401 is on the right in the figures.
  • the front machine 401 is in the release position. Accordingly, the free end of the control lever 403 is pivoted downward about the transverse ski axis 407 and is in the release position. As a result, a locking unit 408 arranged below the transverse ski axis 407 on the control lever 403 and running concentrically around the transverse ski axis is moved backwards and presses the head 441 of the pivot element 420.3 backwards. A rear end of the locking unit 408 is locked in the locking position on the head 441 of the pivot element 420.3. This engagement prevents the spiral spring 436 from pushing the piston 435 and the pivot element 420.3 forward and from being able to move the control lever 403 into its holding position.
  • the control lever 403 In order to move the front-end machine 401 from the release position to the holding position, the control lever 403 can be pulled upwards a little. This is sufficient to release the locking unit 408 from the locking position on the head 441 of the pivot element 420.3. As soon as the latching unit 408 is released from the latching position, the latching unit 408 is moved forward by the spiral spring 436 together with the pivoting element 420.3 and the piston 435. This leads to the fact that the free end of the control lever 403 is pivoted upward and transferred into the holding position. As a variant of this, the tread spur consisting of a base element 404.1 and a wire bracket 404.2 can also be pressed down to move the front machine 401 into the holding position.
  • the base element 404.1 of the tread spur is pivoted about the transverse axis 407 of the ski.
  • the control lever 403 is moved along by a stop 410 of the base element 404.1, which is in contact with a counterpart of the control lever 403.
  • the latching unit 408 is also released from the latching position on the head 441 of the pivot element 420.3, after which the control lever 403 is moved by the spiral spring 436 into the holding position and the front-end machine 401 is moved into the holding position.
  • the front machine 401 is shown in the holding position.
  • the free end of the control lever 403 is therefore a little higher up than in the release position, while the latching unit 408 of the control lever 403 is a little further forward than in the release position.
  • two latching positions 408.1 408.2 arranged one behind the other on a lower side of the latching unit 408 are also located somewhat further forward than in the release position.
  • the front of the two latching positions 408.1 is pulled onto a front, upright edge of the first base plate 430.1 and is latched onto this front, upright edge of the first base plate 430.1.
  • the control lever 403 is locked in its holding position.
  • the base element 404.1 of the tread spur is also pivoted about the transverse ski axis 407, so that the bracket element 404.2 of the tread spur is lowered onto the housing 402 of the front-end machine 401.
  • the front machine 401 is shown in the damper position.
  • the free end of the control lever 403 is therefore moved further upwards.
  • the control lever 403 is pivoted further about the transverse ski axis 407, as a result of which the latching unit 408 of the control lever 403 is also moved further forward and upward.
  • the rear of the two latching positions 408.2 is pulled onto the front, upright edge of the first base plate 430.1 and latched onto this front, upright edge of the first base plate 430.1. Therefore, the control lever 403 is locked in its damper position.
  • the front automatics 401 shown, for example, the stops 412.1, 412.2 on the pivot levers 405.1, 405.2 can also be designed differently.

  • pivot arms 517.1, 517.2 each have an elongated shape and are each mounted on the corresponding pivot lever 505.1, 505.2 in the region of a lower end of the corresponding pivot lever 505.1, 505.2 about an axis (not shown) oriented essentially in the longitudinal direction of the ski.

  • a second essential difference between the front automaton 501 shown here and the front automaton 401, which is in the Figures 28 to 30c is shown, the control of the displacement of the control element 520.3 in the longitudinal direction of the ski.

  • This first vertical axis 548 has at its upper end a rectangular, elongated element 550 which is aligned in the longitudinal direction of the ski and is mounted on the slide 520.4 so as to be displaceable in the longitudinal direction of the ski.
  • This rectangular element 550 extends with its front end into a region of a front end of the slide 520.4. Therefore, when the free end of the control lever 503 is pivoted downward and the locking unit 508 of the control lever 503 is moved backwards, the locking unit 508 does not press a head of the pivot element 520.3, but rather the front end of the rectangular element 550 backwards.
